Title: Cam stopper
Inventor: YAMADA TERUO
IPC: B21D28/34
Filed: 1979-10-16
Abstract: PURPOSE: To cause a cam stopper to deform until there are no more clearances when a cam dashes against the same, and improve shock releasing effect by forming a clearance between the through-hole of a stopper block comprising an elastic material and a predetermined mounting fitting.  
     CONSTITUTION: When pressing is finished, a cam 2 is slided on a die 1 by the restoring force of a spring 3 and dashes against the receiving face 6 of a stopper block 4, which in turn elastically deforms to absorb shock. At this time, it deforms until the clearance 10 between the oblong through-hole 8 extending in the dashing direction of the stopper block 4 and the front end of the bolt 9 of a mounting fitting is virtually eliminated. This prevents the bolt 9 from being deformed or broken. Further, a washer 11 softer than the stopper block 4 is interposed in the stepped part of the head of the bolt 9 and the through-hole 8 of the stopper block 4, whereby damaging is prevented.

IPC: H03K19/003
Filed: 1987-05-29
Abstract: PURPOSE:To decrease the output distortions by suppressing the delay of ths transmission time to an input signal and delaying the rising/falling speeds of an output waveform for a circuit that has a high-speed operation. CONSTITUTION:An output buffer circuit and a pre-buffer circuit Which drives the output buffer circuit are divided into plural pieces respectively. Some of those divided pre-buffer circuits 11 and 12 consist of p and n channel MOS transistors TR21-28 having the channel width or length sufficient to drive output buffer circuits 13 and 14. While other pre-buffer circuits consist of other P and N channel MOS TRs having the channel width or length that is reduced satisfactorily compared with The current capacities of the corresponding output buffer circuits. Thus the distortions of an output waveform can be decreased by making use of the difference and the value of the signal transmission time.

Title: Residual charge removing method
Inventor: KIMURA KAZUHIRO
IPC: G03G21/00
Filed: 1978-10-31
Abstract: PURPOSE:To shorten the waiting time before copying and enhance the controllability, by operating the transfer means and residual charge removing means to remove the residual charge from the photoreceptor, when resuming operation after removing trouble such as jamming, in an electrophotographic apparatus. CONSTITUTION:When jamming occurs in the midst of copying in a transfer type electronic copying machine, a residual charge removing means 2 and a transfer means 6 are operated simultaneously upon start of operation of a photosensitive drum 1 after removing such jamming state. When the photosensitive drum 1 makes one rotation from the start position, the transfer means 6 stops. That is, the electric charge on the photosensitive drum 1 is destaticized at a high efficiency as usual, before the residual charge removing meand 2, by the residual charge removing means by charging with the transfer means 6. Thus, by participating the transfer means in the destaticizing operation, destaticization after troubleshooting may be accomplished efficiently, so that the waiting time may be shortened.

Title: Weld structure obtained by using toothed backing
Inventor: YODA MINEO
IPC: B23K9/02
Filed: 1993-05-12
Abstract: PURPOSE:To provide sufficient penetration by making the surface of the backing rugged with projecting teeth, and to provide high weld strength without quenching the metallic structure of the quenched part. CONSTITUTION:Tooth shapes 3 where triangle shapes are made on the surface 2 of a backing 1 are continuously formed, and the substantial surface area is increased thereby. The penetration to the respective members is increased by interposing this backing 1 between the members, and the weld strength is improved by enlarging the range of the weld zone. The tooth shape 3 which is first melted by the generated arc forms the molten pool at the tooth bottom. The molten metal forming the molten pool is not instantaneously solidified, but gradually solidified by the subsequent arc heat and the molten metal of the wire. In particular, the bottom part which is instantaneously solidified is annealed by the molten metal forming the upper layer.

Title: Production of ethylenic polymer emulsion of excellent heat resistance
Inventor: KATOU TADASHI
IPC: C08F4/00
Filed: 1983-07-25
Abstract: PURPOSE:To obtain the titled polymer emulsion stably in high yields, by emulsion-polymerizing an ethylenically unsaturated monomer by using a specified redox initiator system in the absence of a surfactant. CONSTITUTION:An ethylenic polymer emulsion excellent in heat resistance and particularly suitable as an adhesive is produced stably in high yields by polymerizing an ethylenically unsaturated monomer (e.g., ethyl acrylate) in an aqueous medium in the absence of a surfactant by using a redox initiator system comprising an oil-soluble oxidizing agent and a water-soluble reducing agent (e.g., a combination of cumene hydroperoxide with L-ascorbic acid). Although conventional emulsion-type adhesives or self-adhesive have a tendency toward showing poor resistance to heat or water because a large amount of a surfactant is used in their polymerization, the ethylenic polymer emulsion formed according to the present process is freed from this drawback because the polymerization is performed without any surfactant.
